The crankshaft radial sealing ring (1) is vulcanized into the end cover (2) and can only, therefore, be replaced together with the end cover (2). Do not reuse the end cover (2) with the rear crankshaft radial sealing ring (1) after removal.
The crankshaft radial sealing ring (1) has a protective lip (1s) in addition to the sealing lip (1d). The sealing lip (1d), protective lip (1s) and contact surface (3a) at the crankshaft flange (3) must not be lubricated for assembly!

1 Clean and degrease crankcase (4) and oil pan in the area of the applied sealant as well as contact surface (3a) on the crankshaft flange (3).
2 Clean and degrease sealing surface of new end cover (2).





3 Apply sealant with the squeeze gun in the form of a bead (A) with a height and width of 2.0 mm (±0.5 mm) to crankcase (4) and oil pan.
Use exclusively approved sealants.
Do not spread bead (A). Mount end cover (2) within 5 minutes after applying sealant.
The contact surface (3a) must not be cleaned using abrasive paper since this would damage the surface of the crankshaft.





4 Mount end cover (2) with crankshaft radial sealing ring (1) on insertion tool (6).
Make sure that the protective lip (1s) faces towards the side applying the force and the sealing lip (1d) faces in the direction of the crankcase. Leakage could occur otherwise at rear crankshaft radial sealing ring (1).
The crankshaft radial sealing ring (1) can only be mounted on the insertion tool (6), if insertion tool (6) is fitted together with insertion tool (7).

5 Separate insertion tool (7) from insertion tool (6).
6 Mount end cover (2) with crankshaft radial shaft sealing ring (1) and insertion tool (6) onto contact surface (3a) on crankshaft flange (3).





7 Tighten bolts (2a) gradually in crosswise pattern, then tighten the bolts (2b) - observe tightening torque.
8 Detach insertion tool (6) from crankshaft flange (3).

9 Carefully lift protective lip (1s) and check the correct installation position of sealing lip (1d).
A wrong installation position leads to leakage.
The sealing lip (1d) must point towards crankcase (4) all around its circumference.
10 Check for correct installation position of the protective lip (1s).
An incorrect installation position leads to premature wear of crankshaft radial sealing ring (1).
The protective lip (1s) must point towards transmission housing around its entire circumference.
